Hey Ray, you are correct it is z/VSE that will allow you to cancel the CUU.

With a batch job, cancelling the job takes care of that. But one doesn't want to cancel HSM. :-) The CANCEL MOUNT must be taking advantage of the fact that the step name of the MOUNT-generated STC is the unit address, so it's really not a true CANCEL MOUNT, but a CANCEL STC. Unfortunately, I'm not in a position to try it this at the moment. :-) Later, Ray ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
